The influence of second metal component (Fc) on Pt/KL zeolie catalyst was investi-gated. The catalytic properties of Pt-Fe/KL zeolite varied as the amount of Fe. When the amount of Fe was 0.3 % (mass fraction), the catalyst was found to show both excellent n-hexane aromati-zation reactivity and higher ability for sulphur-resistance. The dispersion of Pt particles was also found to be better in this bimetallic catalyst, whereas the electron state of Pt particles as indicated by CO-FTIR was nlodified to be more electron-deficient than that of Pt/KL zeolite, which made the bimetallic Pt-Fe/KL more tolerant to sulphur poisoning.
